I am simply pointing out that the way you make your argument matters. The way you are arguing (based on the tenor of your comment) will not work. When you make the arguement as you are making it against someone pro GMO you are likely to have just as much luck as a bible thumper has quoting scripture to an atheist during an arguement. It simply won't work. As for growing you own, that is great, I garden as well both as a hobby, and because i don't like what I see out of big ag. Keep in mind though, that if you approach the GMO arguement incorrectly you will be growing GMO whether you want to or not. Simply put the GMO crops will outcompete every heirloom variety available, and in time you'll be growing GMO whether you want to or not. A good boxer is much better at deflecting his opponents attacks than he is at actually landing his own punches, a good political debater must have similar skills or they'll lose before they even get a chance to win. Mine is not a critique of your position, only of how you present it.
